HENRY B. ELLIOTT, OF CINCINNATI, OHIO, ASSIGNOR OF ONE-HALF TO LOUIS N. CI-IIPMAN, OF CINCINNATI, OHIO.

SASI-I-FASTENER.

Specification of Letters Patent.

Application filed May 14, 1915. Serial No. 28,094.

To all whom it may concern Be it known that I, HENRY B. ELLIOTT, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certaln new and useful Improvements in Sash-Fasteners, of which the following is a specification.

This invention relates to windows and has for its object to provide a self opening window.

Another object of the invention is to provide means for automatically raising a lower :sash and lowering an upper sash in a window. Another object of the invention being to provide means whereby the upper and lower sash of a window may be locked in any desired position.

With the above and other objects in view which will be hereinafter more fully eX plained, I have invented the device illustrated in the accompanying drawings in which- Figure 1 is a sectional elevational view of a window embracing my invention, Fig. 2 is a sectional view taken on line A-A Fig.- 1, Fig. 3 is an enlarged detail elevational view of a lock, Fig. 4 is an enlarged fragmental sectional elevational view taken on line B-B Fig. 1, Fig. 5 is an enlarged fragmental sectional view taken on line CC Fig. 1, Fig. 6 is a sectional view taken on line DD Fig. 5, and Fig. 7 is an elevational view of one end of a window sash, Fig. 8 is an elevational View of a modified form of the invention shown applied to a fragment of a window, Fig. 9 is a front elevation of the lock member, Fig. 10 is a side elevation of Fig. 9, Fig. 11 is an elevational sectional view of another modification of the device, and Fig. 12 is a face view of Fig. 11.

Like reference characters indicate like parts throughout the specification and in the several views in the drawings in which- 1 indicates a window having a frame 2 and an upper sash 3 and a lower sash 4. Cords 5 and 6 operate over the pulleys 7 and 8 and are provided with weights 9 and 10 011 one end, the other ends of which are fixed in the usual manner to the window sash 4. Cords 11. and 12 operate over pulleys 13 and 14 and have weights 15 and 16 attached to their inner ends, said weights 15 and 16 operating in the usual pockets 17 and 18 one wall of which is formed by the running boards 19 and '20 between which said sash 3 and 4 operates.

The sides of the sash 3 and 4 are provided with toothed strips 23 and 24. Seated in mortises 25 and 26 in the board are locks 27 and 28 each consisting of a casing 29 having sliding latch bolts 30 and with ends 31 and 31, having an inclined face 32. This bolt is normally pressed into a locking position by a spring 33, the bolt ends 31 and 31 normally engaging the teeth 34 of the strips 23 or 24 whereby said sash is normally held against movement. The bolts 30 and 35 are provided with enlarged heads 36 and 37 against which the bifurcated ends 38 and 39 of the levers 40 and 41 operate to draw the ends 31 and 31 within the casings 27 and 28 whereby said sash may have free movement. A. rectangular opening 42 is provided in the upper end of the lever 40 and a rectangular opening 43 is provided in the lower end of the lever 41, said casings 27 and 28 being so located that said openings will aline so that said openings 42 and 43 will receive the common rectangular shaft 44 the outer end 45 of which projects through an opening 46 in plate 47 and has fixedly mounted thereon a lever 48 to the ends 49 and 50 of which are pivoted pushes 51 and 52 which project through the right angular part 53 of the plate 47. When the push 51 is shoved in both locks levers 40 and 41 are operated but in different directions, the lever 40 in a direction to operate the bolt 30 against the spring 33 while the lever 41 works free however when the push 52 is pushed in the lock levers 40 and 41 will be operated in exactly the opposite direction with the attending opposite results. Now as the weights 9 and 10 connected with the lower sash 4 have a combined weight slightly greater than said sash, it is clear that when the push 51 is operated to withdraw the bolt end 31 the said sash 4 will be raised by the weights 9 and 10 overbalancing the sash, however, as soon as the push is relieved the spring 33 will cause the lock 31 to again engage one of the teeth of the plate 24. But when the push 52 is operated thus withdrawing the bolt 31 from engagement with the plate 23, the sash 3 will slide down by gravity as it is of a sufficient weight to overbalance the weights 15 and 16. The lowering of the upper sash may be stopped at any desired-point by releasing the push, the springs '33 again operating the'bolt 31. The inclination of the face 32 will permit of the sash 4 being lowered without operating the push 51 as the teeth 55 having inclined surfaces to operate thereagainst. will shove in the bolt 31 against the tension of the spring 33. Because of similar construction the upper sash may be raised freely.

In Figs. 8, 9 and 10 I show a slight modification of the invention in which the push arms 56 and 57 of the lever 58 have reduced necks 59 and 60 whereby either one of the other of said arms 56 or 57 may beengaged by the hook 61, slidably secured to the plate 62 by means of a pin 63 projecting through the slot 64 in the hook arm 65 and held connected therewith by the enlarged bead 66. The hook 61 may be engaged with either one of the arms 56 and 57 whereby either one may be held in a pushed in position thus providing means for holding either of the sash locks in an inoperative position whereby the sash may be raised and lowered freely.

In Figs. 11 and 12 is shown a modifica tion of the form shown in Figs. 8 to 10 the difference being thatv the face plate. is pro vided with openings 67 and 68 for the arms 56 and 57 each having a downward projecting reduced extension 69 and 70 into which the necks 59 and 60 may be protected to hold said arms in pushed in position.

Having now described my invention that which I claim to be new and desire to procure by Letters Patent is 1. A sash lock consisting of a pair of spring pressed bolts, racks on a pair of sashes for engagement with said bolts and levers for. operating said bolts, one of said levers projecting up and the other down,

said bolts being spacedapart, one being on a' plane above the other, a common shaft upon which said levers are mounted, said bolts having enlarged heads and levers having forks for engaging said'heads, the fork on said projecting upwardly, lever being on its upper end, and the fork on the other lever being on its lower end whereby the movement of said shaft will operate said levers in opposite directions, means for operating said shaft, said means consisting of a lever centrally fixed to said shaft, means for operating said last lever, said last means consisting of pushes on the opposite ends of said last lever, means for holding said pushes in a normal position, said last means consisting of springs controlling said bolts, means for holding said-pushes against the action of said springs, said last means consisting of reduced necks on said pushes adapted to seat in a slot.

2. A sash lock consisting of a pair of Copies of this patent may be obtained for five cents each, by addressing the spring pressed bolts, racks on a pair of sashes for engagement with said bolts and levers for operating said bolts, one of said levers projecting up and the other down, said bolts being spaced apart, one being on a plane above the other, a common shaft upon which said levers are mounted, said bolts having enlarged heads and levers having forks for engaging said heads, the fork on said projecting upwardly lever being on its upper end, and the' fork on the other lever being on its lower end whereby the movement of said shaft will operate said levers in opposite directions, means for operating said shaft, said means consisting of a lever centrally fixed to said shaft, means for operating said last lever, said last means consisting of pushes on the opposite ends of said lever, means for holding said pushes in a normal position, said last means consisting of springs controlling said bolts, and means for holding said pushes against the action of said spring, said last means consisting of reduced necks on said pushes adapted to seat in a slot, and a pivotally mounted member in which said slot is located.

3. A sash lock consisting of a pair of spring pressed bolts, racks on a pair of sashes for engagement with said bolts and levers for operating said bolts, one of said levers projecting up and the other down, said bolts being spaced apart, one being on a plane. above the other, a common shaft upon which said levers are mounted, said bolts having enlarged headsand levers having forks for engaging said heads, the fork on said projecting upwardly lever being on its upper end, and the fork on the other lever being on its lower end whereby the movement of said shaft will operate said levers in opposite directions, means for operating said shaft, said means consisting of 1 a lever centrally fixed to said shaft, means for operating said last lever, said last means consisting of pushes on the opposite ends of said lever, means for holding said pushes ina normal position, said last means consisting of springs controlling saidbolts, means for holding said pushes against the action of said spring, said last means consisting of reduced necks on said pushes,

adapted to seat in a slot, and a pivotally mounted member in which said slot is located, said member arranged to engage either of said pushes.

In testimony whereof I affix my signature in presence of two witnesses.
